in grin-miner, the only difference is to choose the “right” plugin. another option to start the miner is to invoke your start script from cron add the following line in your user’s crontab @reboot $HOME/startmining.sh the grin-miner start script can look like this (i’ve used tmux instead of screen) $ cat $HOME/startmining.sh #!/bin/bash tmux new-session -d -n mining tmux send-keys -t mining “cd $HOME/grin-miner” C-m tmux send-keys -t mining “./grin-miner” C-m ---

dude i don’t get this it is almost 2 am and i am loosing my mind… i set up everything so far with all the necessary upgrades, drivers miner is working and it shows the rtx 2080ti but status is errored i suppose it is because the gui is not turned off has anyone a video tutorial where i can see how to start the miner without the gui on linux 18.04 please? ---

II’m afraid there is no such kind of video. The steps I described in my previous message are easy to repeat, please try it. Open a terminal in your Ubuntu, perform a ‘sudo systemctl set-default multi-user.target’ command and reboot. All you need after that (but you can do it in advance) is to configure your .toml file. Here is my example: [https://pastebin.com/VD0gD0qw](https://pastebin.com/VD0gD0qw) Pay attention to lines 43 and below (mining pool configuration) and 176 and below (mining device(s) configuration). CPU mining part (lines 79-82) should be commented with #. ---

okay thanks mate will try after work today can i not just put plug the monitor in the vga on-board card adapter and try it to run it from there if this does not work for some reason? ---

It will work, trust me. ) You can connect the monitor to your 2080Ti card without any problems. ---

Is the cuda PATH also set? When you reboot the machine open terminal and check “nvcc -V” works. If not then your CUDA PATH is not set. ---

not sure mate i installed CUDA and the miner is definitely working what happens if you do not set up the cuda PATH? ---

the miner turned off in the middle of the night for no reason and i had a matrix screen… is that normal? any experiences with this? ---

Hi guys, I’m getting the strange figure of 3 GPS (C31) from an NVIDIA P6000 (has 24GB ram), but no shares submitted, and if I try to run 2 instances of the CUDA plugin, it says ‘out of memory’, but if try openCL it runs (slowly, but does run). Any ideas? ---

i don’t have access to it anymore, i was using a VPS, and they blocked me because i shouldn’t be using it to mine cryptos anyway… but i’ll try to grab the hold of another card with 24 or 32GB ram… that’s what i’m aiming for now! ---
